ELEVATOR AND DUMP.

SPECIFICATION forming part of Letters Patent No. 532,022, dated January8, 1895. Application filed August 23, 1894. Serial No. 521,056. (Nomodel.)

To all whom it may concern:

Be it known that I, RUSH BULLIs, of Milton, in the county of Rock andState of Wisconsin, have invented a new and useful Improvement inElevators and Dumps, of which the following is a description, referencebeing had to the accompanying drawings, .which are a part of thisspecification.

My invention has relation to improvements in elevators and dumps, havingparticular reference to devices for elevating and dump- 1ng gram.

The main objects sought to be attained are simplicity in constructionand rapidity of action, and in connection therewith strength anddurability.

The invention also contemplates the provision of simple means fordumping the load automatically, the construction being such that thedumping can be efiected at varying heights.

With the above objects, and others, in view, the invention consists ofthe devices and parts, or their equivalents, as hereinafter more fullyset forth and claimed.

In theaccompanying drawings, Figure 1 is a longitudinal verticalsectional view of the complete device. Fig. 2 is a front elevation ofthe upper portion thereof. Fig. 3 is a view of the rear side of the car;and Fig. 4. is a cross section taken in front of the car.

Like numerals of reference denote like parts throughout the severalviews.

Referring to the drawings, the numerals 5-5 indicate the side beams of ascaffold, connected at their upper ends by a transverse beam 6. The sidebeams form the outer rails or ways of my improved device, and'areconnected at regular intervals by cross strips 7. Intermediate the outerrails 55, and secured centrally to the cross strips 7 is a single fiattrack 8, which extends partially the longitudinal length of thescaffold. This central track is preferably composed of a series ofsections, as shown clearly on the drawings, se-

cured end to end in any desirable manner, and

thereby permitting the track to be readily shortened or lengthened.

The numeral9 indicates a car or receptacle, having its rearsideinclined, as clearly shown. To this rear side are secured, at oppositeedges, angle brackets 10 40, the depending flanges of which are adaptedto fitagainst the v inner sides of the outer tracks or rails 55. At thelower end of the inclined rear side is provided an exit opening 11, andbordering the side edges of this opening are angular strips l212. At therear of the depending flanges of these angular strips is j ournaled atransverse shaft 13, upon which is hung a gravity opening door 14.

In suitable recesses 1515 at the lower end of the car are mountedrollers 1616, said rollers, in the travel of the car along the trackway,diminishing the friction materially at the points where the greatestfriction would necessarily occur. At the upper end small blocks 17 -17are secured, so as to dispose the car on a perfectly level plane.

Secured to the inner side of the rear piece of the car, near the upperedge thereof, is a doubly grooved pulley l8, and'rnounted in the uppertransverse beam 6 is a similarly grooved pulley 19. attached at itsupper end to one of the cross strips 7. This cord is then extendeddownward and around one of the grooves of the pulley 18, thence upwardlyand around one of the grooves of the pulley 19, thence down again andaround the other groove of the pulley l8, thence up and around the othergroove of pulley 19, and finally extended laterally and downwardly andaround a singly grooved pulley 21 mounted in one of the side tracks 5.The free end of the cord or rope is preferably passed around anotherpulley (not shown) at the base, the cord being in convenient posi tionfor manipulation by the operator.

The numeral 22 indicates a hopper for catching the grain as it isdischarged from the car. This hopperis provided atone end with hooks2323, which are adapted to engage the crossstrip 7 where the centraltrack 8 terminates.

Pivoted to the center of the opposite edge of the hopper is a long hook2%, the freeend of which is adapted to engage a pin 25 projecting fromthe next cross-strip above.

In use, my improved device may be arranged inoperative position eitherwithin a granary or outside thereof. In either case, the scaffold is,preferably, of sufficient length to admit of the upper end thereofextending'up to the top of the store room, and to rest against, or besupported by, the beam or rafter 26, as

An operating cord or rope 20 is shown in Fig. 1. \Vhen the car isproperly adjusted to the trackway, it will be seen that the rear sidethereof rests upon the top edges of the side tracks or ways 55, whilethe depending flanges of the angle brackets 10 rest against the sides ofthe tracks or ways. This latter prevents sidewise displacement of thecar. The door 14 bears against the central track 8, and is normally heldclosed thereby. Afterthe car is filled with grain, and it is desired toelevate the same to an upper story of the granary, a pull is given tothe operating cord or rope, and this causes the rapid ascent of the carup the inclined way. As soon as the car reaches the end of the centraltrack 8, however, all support for the door 14 is removed, and of coursesaid door immediately drops by gravity, and the grain is emptied throughthe exit opening 11. If the hopper 22 is used, the grain, of course, isemptied directly therein, and may be conveyed therefrom to any part ofthe room by means of a suitable piping coupled to the hopper. I do notwish, however, in any sense, to be understood as limiting myself to theuse of my invention in connection with this hopper, as it .is obviousthat, if preferred, the grain can be emptied directly onto the floor, ormay be dumped directly into a suitable pipe, and conveyed thereby to anyportion of the room. As soon as the car is emptied of its load, the cordor rope is allowed to slip through the hands of the operator, and thecar, of course, will descend the incline by gravity, the door letimmediately closing automatically as soon as the car begins to descend,by reason of the contact of said door with the end of the central track8.

If it is desired to dump the load at greater height than that shown inthe drawings, of course all that is necessary to be done is to attachanother length of the central track 8, while if it is desired to dump ata less height, a length of said track is removed.

As the depending flanges of the angular strips 12 fit against oppositeedges of the door, it is evident that if the contact of the door withthe central track does not have the effect of fully closing said door,said depending flanges will prevent any leakage of the grain during thetravel of the car.

that I provide a most simple and rapidly working device, of suchconstruction that the 1 load may be elevated with a minimum amount 3 ofpower and in which the dumping is effected with the slightest possibleloss of time.

While I have described my device as having particular reference to meansfor elevating and dumping grain, yet it is apparent that the same may beconveniently used as an elevator for freight, and in fact all kinds ofgoods and commodities.

Having thus described my'invention, what I claim, and desire to secureby Letters Patent of the United States, is
